Course Details

Using hands-on examples, this one-day course demonstrates the use of Simulink products to design common communication systems. The emphasis is on designing end-to-end communication systems using Simulink®, Communications Toolbox™, and DSP System Toolbox™.

Topics include:

  • Modeling using Communications Toolbox
  • Analyzing the bit error rate (BER) of a communication system
  • Adding channel impairments
  • Designing receiver algorithms
